This paper presents a comprehensive study and experimental validation of an integrated high-efficiency power architecture for electric vehicle (EV) applications. The proposed system simultaneously optimizes battery charging algorithms and onboard low-voltage DC-DC conversion. On the charging side, we evaluate three techniques Conventional Constant Current–Constant Voltage (CC–CV), Multistage Constant Current (MSCC), and MSCC with Reflex Charging using a 72-cell lithium-ion battery model. The MSCC + Reflex approach achieves a 38% reduction in charging time and 23% lower energy loss compared to CC–CV.
